Nov 12, 20182000 All Series Weather Stations - Product Manuals
Thank you for purchasing a WatchDog 2000 Series Weather Station. The stations are completely weatherproof and feature 12-bit resolution for higher accuracy. The stations can be accessed at different times by multiple users because the data is not cleared from memory following a download. The 2000-Series weather stations can communicate via direct-wire, radio or telephone connections.
Current weather conditions, historical data, and computed parameters are easily viewed on the station’s LCD screen. The station LCD can also be programmed to display a variety of plant disease infection potentials. The arrow keys can be used to pro-gram the station’s logging interval and assign sensors to the external sensor ports. You can also scroll through the sensor readings, Degree Day/Chill Hour calculations and set your temperature ranges.

PRODUCT MANUAL
Models
1650, 1525, 1450, 1425,
1400, 1250, 1225, 1200, 1115
NOTE: All models of the 1000 Series stations have four external ports. For most models, one or more are not used. They are present on all models to simplify manufacturing and to retain the port plug securely (see below).
This manual describes how to use your WatchDog Station and how to keep it working accurately for many years. Read this manual thoroughly in order to make effective use of your data logger.
The WatchDog Micro Station series will allow you to record and visually monitor environmental conditions at remote sites. The WatchDog’s liquid crystal display (LCD) eliminates the need to download the data logger to observe current conditions.
These stations give you the flexibility to change external sensors as your needs vary. Simply plug the sensor into the station port and configure the station to the corresponding sensor through the software.

Oct 01, 20186120 Soil Compaction Product Manual - Product Manuals
Soil compaction can occur in any type of soil. Years of traffic and tillage
can cause soil particles to group together and fill in air spaces in
the soil creating a “plow pan” below the tillage area. When this happens,
a hard layer is formed making it difficult for moisture and roots to
penetrate the soil.

Jul 03, 20186435_TDR_350_manual - Product Manuals
Thank you for purchasing the Field Scout TDR 350 soil moisture, electrical conductivity and soil surface temperature meter. This manual describes the meter's general features and operation. Soil moisture is a critical, and potentially highly variable, component of the soil environment. Time domain reflectometry is a proven technology for quickly and accurately determining volumetric water content (VWC) in soil. Electrical conductivity (EC) is a function of the moisture and salt in the soil. The meter also measures soil surface temperature. The user can quickly transition between taking VWC readings in standard and high-clay mode.

Oct 10, 20173613ARS Digital Temperature RH Sensor with Aspirated Radiation Shield - Product Manuals
Thank you for purchasing a Digital Temperature/RH Sensor with Aspirated Radiation Shield (ARS). To ensure temperature and humidity sensors output accurate meteorological data, they are usually housed inside a radiation shield. However, solar radiation of the surface of the shield will lead to the interior being heated above air temperature. Under outdoor conditions, natural airflow is usually sufficient to ensure air temperature readings are accurate. But when the sensor is located indoors (such as in a greenhouse), the air is often stagnant, which leads to insufficient circulation. The solar-powered fan forces air through the shield to ensure that the sensor is measuring ambient air.
